Security Advisory Description CVE-2026-53393 In the Linux kernel, the following vulnerability has been resolved: nfsd: reset write verifier on deferred writeback errors nfsdvfswrite and nfsdcommit both call filemapcheckwberr to detect deferred writeback errors, but neither rotates the server's...

The vulnerability of the dpu_writeback_init() function in the drivers/gpu/drm/msm/disp/dpu1/dpu_writeback.c file of the Direct Rendering Infrastructure (DRI) driver in the Linux operating system’s kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the dpuwritebackinit function in the drivers/gpu/drm/msm/disp/dpu1/dpuwriteback.c file of the Direct Rendering Infrastructure DRI driver in the Linux operating system is related to the assignment of a pointer with an expired lifetime. Exploiting this vulnerability could allow...
